SEEOIFIGATION forming part of Letters Patent No. 680,7 55, dated August20, 1901. Application filed Tune 19, 1900. Serial No. 20,862. (Nomodel.)

To all whom it may Cull/067:

Be it known that I, JOHN S. BLOOM, a citizen of the United States,residing at Winthrop, in the county of Buchanan and State of Iowa, haveinvented new and useful Improvements in Machines for Crushing andCutting Corn, of which the following is a specification.

This invention relates to new and useful improvements in machines forcutting and crushingcorn; and its primary object is to provide a deviceof this character which is simple and durable in construction, whichmaybe readily operated, and which is effective in use.

The invention consists in a hopper having a transversegrinding-partition and in its lower end a pair of rollers provided withlongitudinal radial blades having peripheral cutting edges and an Lflange or base,whereby the blade is secured to the roller, the flangecovering the roller between the blades and the edge of the flangeabutting against and aiding to support the next blade, and equaleugaging gear-wheels arranged so that the rollers revolve with theopposing blades always in register.

I have fully and clearly illustrated the improvements in theaccompanying drawings, wherein- Figure 1 is a side elevation showing theinterior construction of the frame and the coacting cutting and crushingrollers. Fig. 2 is a central longitudinal section. Fig. 3 is a planview. Fig. 4 is a similar View thereof with the hopper detached, andFig. 5 is a detail view of a cutting-blade.

Referring to said figures by numerals of reference, 1 is the frame ofthe device, upon the cross-strips 2 of which are mounted suitable sidepieces 3, between which is mounted a hopper 4, which extendstransversely of the machine. This hopper is provided at its center witha strip 5, extending thereacross, and at points below the same arejournaled cyl- 1 These I inders 6 of particular construction. cylindersare preferably formed of wood and have trunnions 7, which are journaledwithin boxes 8, secured to the cross-strips 2, hereto fore referred to.The boxes of one of the cylinders are slotted at 9 for the reception ofthe securing-bolts 10, whereby the cylinder mounted in the slottedbearings may be moved to and from its mate, as desired. A gear 11 issecured to the end of a trunnion '7 of each cylinder 6, and these gearsmesh, and thereby cause the cylinders to rotate in unison and the bladesthereon to always register.

Each cylinder 6 is provided with .a desired number oflongitudinally-extending blades 12. These blades are substantiallyL-shaped in cross-section, one portion 13 thereof being madeconvex-concavo to fit the circumferential face of the wooden cylinder,and is provided with a suitable number of perforations 14 for thereception of suitable securing means, as bolts. The other part 15 of theblade is sharpened and is adapted to project radially from saidcylinder, as shown. will be seen that the section 13 of the blade isslightly curved, so as to conform to the curvature of the cylinder towhich it is attached, and these blades are all arranged, preferably, asshown in Fig. 2, with the edge of the flange abutting against the nextblade, and it will thus be seen that the sections 13 thereof form acontinuous metallic casing about the cylinder.

The gears 11 are preferably secured to their trunnions by means ofset-screws or in any other suitable manner, and it will be understoodthat the same may be detached and smaller or larger gears substitutedtherefor. The gears, it will be perceived, are so arranged that therollers will be re'volved with the blades always in register.

A suitable trough, as 17, is arranged within the frame 1 at a pointbelow the cylinder 6 for the reception of the corn after the same hasbeen operated upon by the machine. A hand-wheel 18, having a handle h,is mounted upon the trunnion of one of the cylinders 6, and it will thusbe seen that the device may be readily operated manually.

Corn is fed to the hopper in any suitable manner, as through a trough19, and will, as is obvious, be turned into an upright position bythecross-strip 5. The cars will therefore be fed between thecylinderse'nd first, and the blades thereof are so arranged as to cut inunison.

It will be seen that by adjusting the boxes 8 so as to carry the rollermounted therein toward its mate the blades 15 may be made to 0verlap,andthe'cylinders will thus be brought closely together and the crushingaction thereof will be greater. The material after leaving the cylinderswill, as is obvious, fall into the trough l7.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein Without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination in a machine for cutting corn-ears into pieces, of ahopper, a transverse grinding-partition in the lower end of the hopper,a pair of rollers each provided with longitudinal radial bladespresenting peripheral cutting edges, each blade havingan L flange orbase, whereby it is secured to the perimeter of the roller, said basecovering the interval between the blades, and abutting against, andaiding to support the next blade, and the equal engaging gear-wheelswhereby the rollers are caused to revolve with their opposing bladesalways in register.

In testimony whereof I affix my signature in presence of two witnesses.
